Response

Extent and Result of Searches to Locate Information

To locate the information relevant to your request searches were conducted within North Yorkshire Police. I can confirm that the information you have requested is held by North Yorkshire Police.

Decision

I have today decided to disclose the located information to you.

Leather isn’t a surface type that lends itself to chemical treatment. Soft leathers, textured or patterned are not usually authorised, unless its exceptional circumstances, and then it’s to assess suitability. Patent, glossy leather with a smooth surface can be treated, and if anything, we may consider treatment if there are plastic windows on the inside of wallets/purses.
